IMPROVEMENT IN MACHINERY FOR GORING SHCE-UPPERS.

` Specification forming part of Letters Patent No. 141,642, dated August12, 1873; application iiled Aprn 11, im.

To all whom it may concern:

Be it known that I, AsAEEL J. GOODWIN, of Brookline, of the county ofNorfolk and State of Massachusetts, have invented a new and usefulImprovement or Improvements in Machines for Goring Shoes; and do herebydeclare the same to be fully described in the following speciiication,and represented in the accompanying drawings, of which- Figure l is atop view of the table of a shoegoring machine with my invention appliedthereto. Fig. 2 is a front elevation, and Fig. 3 a longitudinal section,of the above. Fig. 4 is a top view, Fig. 5 an end view, and Figs. 6 and7 opposite edge views, of the guidepattern.

Such other gures as may be necessary to the complete illustration of myinvention will be hereinafter referred to and described.

The present invention has reference to the machine described in LettersPatent No.133, 708, dated December 10,1872, and granted to myself andJames H. Gardiner, and vis for the purpose of improving such machine, orrendering it more convenient and useful.

The guide-pattern shown in Figs. 4, 5, 6, and 7 is to be operated orraised and depressed in manner or by means substantially as described inthe said patent with respect to the guide-pattern therein explained; butmy present guide-pattern is so constituted as to admit of its beingincreased or diminished in width at either end, so as to vary theangular position of its opposite edges, whereas in the guide-patterndescribed in the patent, though capable of being increased or diminishedin width, the opposite edges always maintained at their normal angle orthe same angle with each other. The guide-pattern is also provided withgrooves in its opposite edges to receive what are or may be termed sizeslips.7 The table is furnished with adjustable slides and elasticlever-gages for iixing or determining the position of a gore on suchtable. Such table also has a lining gageholder and certain mechanismconnected therewith, as hereinafter described.

In the drawings the table is shown at A as iixed upon and extended abovea platform, B. .The gore and the parts with which it is to be connectedby paste are to rest on the top of such table. The table is groovedlengthwise to receive two iiat slides, C C, ar-

ranged as shown, each of which, with its groove, is dovetailed intransverse section. The slide fits closely lin or to the groove, and

may have a spring or friction brake to hold it in position or prevent itfrom accidentally moving lengthwise out of place.

Fig. 8 is an under-side view of one of the said slides C, showing itsspring-lever gage D, which is an elastic lever, bent up at its frontend, as shown at a in Fig. 9, which is a section longitudinally throughthe slide C and the gage D. The latter is pivoted at b to the slide, andis sprung or bears closely against the bottom of the'slide. By means ofthe slides and the gages the stops or rests a. a may be adjusted to anydesirable positions to indicate the points at which the upper corners ofthe gore are to be placed on the table. The guide-pattern is shown at Eas made in two parts, b c, each of which has a dovetail groove in itsouter edge, as shown at d, to receive a slip of pasteboard, e, termed asize slip, which, tted in the groove, has size iigures and marksarranged upon it to indicate for setting the stops a' a to differentpositions, as may be required. for gores of different sizes, andespecially what are termed right-and-left gores. The two parts b c areconnected. by clamp-screws e e and slotted arms ff, arranged as shown.The arms extend from the part c over the part b, and are provided withslots g g to receive the shanks of the screws, which pass through theslots and screw into the part b. The slots are either curved or madewider than the diameters Of the screw-Shanks in order to admit of theangle of the outer edges of the parts b c being varied, as occasion mayrequire, to adapt the-guide-patterns to the form of the gore. The lininggage and holder is shown at F as composed of two thin plates, lm,projecting from a T-piece or carrier, G, and fastened thereto byScrew-clamps n a. The shank o of the carrier G extends through theshorter arm p of a lever, H, fitted to slide upon a fulerumshaft, I, andsecured thereto by a clampscrew, p. The pivots g g of the said shaft aresupported by a frame, fr, erected on the platform, and shaped as shown.Furthermore, the said shank o slides on the longer arm s of the lever H,and is provided with a retractive spring, t, iixed tothe shank and thelever. A lever-clamp, K, pivoted to the head of the arm p of the leverH, serves to force the lining-gage F down uponthe lining when on thetable and preparatory to said lining being turned over and down upon thelininggage. A line or band, u, xed at one end to the shank o, passesalong underneath such shank and down through the rear arm of a bent1ever, L, formed and arranged within the arm p, as shown. The draft-lineu from thence goes down through a slot, c, in the platform, and thencethrough a pulley, w, attached to a treadle, M; thence the draft-line isto continue and pass up through the platform and to and through anothersuch lever, L,and to another carrier, G, to be arranged on the otherside of the table. There is to be to the table a duplicate lining-gageand its operative mechanism, all being placed opposite to such, ashereinbefore described, both gages being worked or moved forward ortoward each other simultaneously by one treadle, the extent of advancemovement of each being regulated by an adjustable collar or stop, x,upon each of the arms s, and held thereto by a set-screw, y. Thegage-carrier G brings up against the stop w, at the termination of theadvance movement of such carrier.

On depressing the treadle the draft-line will not only advance thecarrier G, but will so move the bent lever L as to force and hold thecarrier upward, in order for the carrier to raise the lining-gage,during its advance, so high above the table as to keep such gage freefrom, and cause it to pass over, the piece of cloth or lining laid uponthe table, the lininggage being subsequently depressed upon the saidlining by the lever-clamp K, moved by an attendant.

There extends up from the frame r a rail, z, arranged as shown, a screw,a', being screwed into and through the arm s of the lever H. By means ofthe said rail and screw, the degree of pressure of the lining-gage` uponthe cloth may be regulated. There is to the lining-gage F what I termthe lap-holder and gore-gage N. It serves not only to hold down the lapor part of the lining turned over and down upon the gage F, but as anadditional gage or guide for determining the position of the gore. Thelap holder N, shaped as shown, slides lengthwise on the carrier of thelining-gage, and underneath a cap, O, fastcned upon the carrier byscrews, and formed as shown, it being provided with a small abutment orstop, b', the cap O, with the stop b', being adjustable on the carrier Gin the direction of the shank c of the lap holder. From the saidshank ca small stud, d', projects, as shown. It, by bringing up against thestop b', determines the extent of advance ot' the lap-holder. While thestud is advancing, it rises up and over an inclined plane, e', carriedby an arm, f', pivoted to the cap O.

Fig. l0 is an inner side view of such arm f and inclined plane c. Thetwo I term the dog P v The stud and inclined plane thus serve to raisethe lap-holder during its advance, in order that it may pass freely overthe lining lap, it being caused, by the elasticity of its shank, to falldown upon the lap as soon as the stud d may have passed beyond theheadof the inclined plane. On retracting the lapholder, the stud d will passunderneath the inclined plane and raise the dog.

With the above-described mechanism, the goring-machine may be adapted togores of different sizes or styles, and be used to properly arrange thegore with the parts of the upper for which it is to be pasted, and,furthermore, the edges of the lining of the upper may be folded over orlapped, and prepara tory to the gore being pasted to the upper, all ofwhich will be readily understood by those who are accustomed to themaking or using of the machines to which my invention or improvementsappertain.

What I claim as my invention is- 1. The guide-pattern E, having itsparts b c connected by slotted arms f j' and clampscrews e e, arrangedas and for the purpose substantially as specified.

2. The guide-pattern E, provided with the size slip-receiving grooves dd, arranged in it as set forth.

3. The table A, provided with the slides O O and the elastic levergagesD D, all constructed, arranged, and applied together substantially asspecified.
